they would be the type that would go inside a plush toy or maybe a talking picture frame. It could be used in a greeting card but it would be somewhat thick. This one has a circuit board, a record button, a play button, a microphone, a speaker and 3 watch style batteries.

Awesome. Is there a way to swap out the batteries? It probably wouldn't be necessary, I have 15 year old Godzilla figures that still flash and roar when you wave in front of them, but I figured that would be a neat thing to try and work into a sculpture project.

I made a base entirely out of clay for my first talking one but it wasn't vey sturdy. I made a box for the next one and covered it with clay but it wasn't very functional. Believe it or not, this one is a cardboard box for a vhs tape that I covered in clay and baked which is why it opens on the bottom. Of the 3 talking sculpture I have done, this one is by far the best setup for the electronics. The trickiest part of all of it is designing your box with a spot to hold the play button. It's tricky because only the button can be on the outside with the wires and everything else being on the inside of the box. What makes it tricky is the fact that you have to be able to cook it FIRST and then have the button held securely on the outside of the box with everything else hidden inside after it is already hard. It might not seem tricky but it is.

Thanks, this stuff is fascinating. I've been toying with the idea of making electronics-enriched sculptures for a while, and now that I'm actually starting to sculpt things it's been on my mind more often lately. Maybe you should write up a journal post or an Inscructible about this process when you feel like you've got the kinks worked out.

Actually, there were no kinks with this last design and the electronics I used. It is like a perfect match. The problem is that I don't know if I could find another box like that and to be honest, I hate using bases. I am not talented enough to make them look nice so they just look awkward. They are however necessary unless you want to make a really big sculpture.
